More so, the Raved, Rabeinu Yonasan, Rashba (who quotes the Raved), Ran, Ramban (see Gaon Yaakov, Eruvin 6), and Meiri (Eruvin 20, 22a) maintain that if we have mechitzos that are omed merubeh al ha’parutz (as opposed to shem daled mechitzos), even Rav Yehudah would agree lo asu rabbim (this was only realized when the aforementioned Rishonim’s Chiddushim were published). [From this we see that the Bais Ephraim and the Chazon Ish were guided min hashomayim. They stated that only the Ritva explicitly states Yerushalyim was omed merubeh al ha’parutz and we paskenasu rabbim like Rav Yehudah which is not contradicted by any of the Rishonim discovered recently.]
